Abstract
The invention discloses a power supply with a self cleaning function. The power supply comprises a rotating speed monitoring unit, a processing unit, a load detecting unit and a storage unit, wherein the rotating speed monitoring unit monitors the rotating speed of a power supply fan motor, and obtains the rotating speed of the current power supply fan motor, the processing unit obtains motor rotating speed information transmitted by the rotating speed monitoring unit, the load detecting unit detects the current power supply load and the current converting efficiency, the storage unit stores normal work data of the power supply, and the normal work data is the corresponding relationship of the current converting efficiency and the power supply fan motor rotating speed corresponding to the power supply load. The processing unit compares the normal work data with the corresponding relationship of the power supply fan motor rotating speed in the storage unit according to the current motor rotating speed information and the actually measured power supply load and power supply converting efficiency, if the corresponding relationship is exceeded, the condition that the dust deposition of the current power supply fan is serious is judged, and the processing unit controls the power supply fan to accelerate the rotating speed for blowing deposited dust out of the power supply.
Description
Technical field
The present invention relates to a kind of power supply with self-cleaning function.
Background technique
Along with the use of computer, inner dust stratification problem almost cannot be avoided, and especially cabinet inside is due to the relation of electric field, all fans are dust stratification all easily, causes the burden of fan to increase, and rotating speed raises, long-term overload operation, causes noise to rise, and even likely affects the working life of fan.
Under prior art condition, dust stratification, can only labor cleaning once be formed, very unhygienic, easily causes the health problem of people.And waste time and energy.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of power supply with self-cleaning function of development, have: the monitor speed unit of monitoring power supply fan motor rotating speed, obtain the rotating speed of current power fan motor; Obtain the processing unit of the motor rotary speed information of described monitor speed unit transmission; Load detecting unit, detects current power load and current conversion efficiency; Storage unit, stores the normal operational data of power supply; This normal operational data is the corresponding relation of the power supply fan motor rotary speed corresponding with current conversion efficiency and power source loads;
Described processing unit, according to the power source loads of current motor rotary speed information and actual measurement and power supply conversion efficiency, compares with the corresponding relation of power supply fan motor rotary speed in storage unit; If exceed described corresponding relation, judge that current power fan dust stratification is serious; Described processing unit controls power supply fan increases rotating speed, and dust stratification is blown out power supply.
Described power supply fan motor is also connected with a polarization motor; When processing unit judges that current power fan dust stratification is serious, the polarization motor described in control unit starts, is that power supply fan produces delicate variations, shakes off dust; Coordinate the fan of full-speed operation, dust is blown out power supply.
Also there is temperature detecting unit; The operating temperature of real-time detection current power; Accordingly, under also storing nominal operating condition in described storage unit, the corresponding relation of temperature and power supply fan motor rotary speed;
The fan motor rotating speed of actual measurement and the corresponding relation of temperature and storage compare by processing unit, and whether dust stratification is serious to judge current power fan.
Owing to have employed technique scheme, a kind of power supply with self-cleaning function provided by the invention, by setting up fan speed data storehouse during normal work, can judge when front fan whether dust stratification accurately, and the order of severity of dust stratification.By adding polarization motor, effectively can coordinate the fan of full speed running, dust is removed.The technology maturation adopted, structure is simple, with low cost, has very positive meaning, is very suitable for promoting on a large scale and using.
Accompanying drawing explanation
In order to the technological scheme of clearer explanation embodiments of the invention or prior art, introduce doing one to the accompanying drawing used required in embodiment or description of the prior art simply below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
